Mayweather and Pacquiao Top Facebook's List of 2015's Most Talked-About Athletes

Facebook has revealed the most talked-about athletes and events of 2015 as part of its annual year in review.

Unsurprisingly, given the hype around the "Fight of the Century" in May, boxers Floyd Mayweather Jr. and Manny Pacquiao top the list.
